Rosin: All you need to know about this interesting concentrate

The origins of rosin are still debated, but it was first introduced to the cannabis community in 2006 via ICMag. It quickly gained recognition in 2015 when Phil “Soilgrown” Salazar, known as @soilgrown_solventless, accidentally discovered this extraction technique while trying to make low-grade hash.

By applying heat and pressure to the hash, Salazar noticed that the resin oozed out, resulting in what is now known as rosin. Over the years, rosin production has evolved, with the use of industrial screens and presses to create larger quantities and more consistent products.

What is rosin?

Rosin is a solvent-free extract that uses heat and pressure to extract compounds from the trichome glands of the cannabis plant, such as cannabinoids (like THCA) and terpenes.

Unlike other concentrates, rosin does not require the use of external solvents, making it a safer option. The temperature and pressure applied during the extraction process determine the color and consistency of rosin.

One of the main advantages of rosin is its convenience and accessibility. It can be produced at home with minimal investment, allowing home growers to make the most of their trimmings, a by-product that is normally discarded. In addition, rosin can transform low-quality hashish into a concentrate suitable for dabbing.

Types of rosin

There are several types of rosin that can be produced depending on the starting material used. The choice of material affects the presence of plant contaminants and consequently the quality of the final product.

Flowering rosin

Flowering rosin is made from cannabis buds and often contains small contaminants of plant material.

These contaminants change the flavor of the dabbing and rosin, producing a burnt taste. To minimize the presence of plant material in flowering rosin, a rosin sieve or mesh bag can be used during the extraction process.

Kief Rosin or dry-sieved hashish

Dry-sieved kief rosin involves an additional step in which the trichomes are separated from the buds before being exposed to heat and pressure.

This additional step ensures a cleaner product, free of plant contaminants.

Rosin Bubble Hash

This is an excellent option for using low quality hash that still contains some plant contaminants. Although high quality hashish is not usually converted into rosin, bubble hash can easily be transformed into a tasty dab.

Fresh Frozen Hash Rosin

This type of fresh frozen rosin is highly sought after due to its high retention of cannabinoids and terpenes. It is generally made from frozen buds, preserving the chemical profile of the strain.

The process consists of making frozen hash from fresh plant material and then using specific micron bags for rosin extraction.

What is the difference between live resin and live rosin?

Live resin refers to a solvent-based extract, usually made from BHO, that is produced from fresh or freshly frozen plant material. The extraction process captures the terpene and cannabinoid profile of the plant before drying and curing.

On the other hand, live rosin maintains the chemical profile of the strain without the use of solvents, resulting in a flavorful concentrate without potentially harmful chemicals.

How is rosin consumed?

There are several ways to consume this interesting concentrate. Here are some of the most popular methods:

Smoking and Dabbing

It can be smoked in a pipe or rolled in a joint to enjoy the experience in the traditional way. However, the preferred method of consuming rosin is dabbing.

Dabbing involves heating a nail or banger with a blowtorch, applying rosin to the heated surface and inhaling the resulting vapor. This method provides an intense and immediate effect.


For a more controlled and discreet experience, you can vaporize using a vaporizer designed specifically for concentrates. These devices allow you to enjoy the flavors and effects of rosin without the need for an open flame or blowtorch.

Incorporate rosin into edibles and topicals.

In addition to immediate consumption, it can also be used to infuse edibles and create topical treatments. By adding rosin to your favorite recipes or skin care products, you can enjoy the benefits of cannabis in a different way.

Effects of rosin

The effects of rosin vary depending on the strain used and the cannabinoid and terpene profile of rosin.

As a highly concentrated product, it should be consumed with caution, starting with small doses and gradually increasing if necessary.

The effects of rosin are usually felt quickly and provide potent therapeutic properties for medicinal patients seeking fast-acting relief.


Rosin extraction offers a convenient and safe method for producing cannabis concentrates at home.

With minimal equipment and a simple process, you can create your own high-quality rosin from a variety of starting materials. Whether you prefer flower rosin, hash rosin or live rosin, the versatility of this solvent-free concentrate will provide you with a flavorful and potent experience.

Remember to start small and experiment with different strains to find the type of rosin that best suits your preferences and needs.
